+TN6 IS FOR COMMUNICATING OVER THE NET
+WITH LINE AT A TIME SYSTEMS SUCH AS MULTICS.
+IT IS LIKE TELNET, WITH THE FOLLOWING CHANGES:
+
+INPUT IS NOT SENT TO THE FOREIGN HOST UNTIL YOU HIT RETURN.
+LINEFEED SENDS THE INPUT OFF WITHOUT A NEW-LINE SEQUENCE AT THE
+END.
+RUBOUT IS DONE LOCALLY, AND ON DISPLAY TERMINALS THE LINE IMAGE
+IS CORRECTLY MAINTAINED.
+CONTROL/V RETYPES THE LINE IN CASE YOU'RE NOT SURE WHAT YOU'VE
+RUBBED OUT.
+^P ERASES THE SCREEN. (ON A DATAPOINT, USE CONTROL/ZERO.)
+^K KILLS THE CURRENT LINE.
+^U AND ^L ARE USED FOR CASE SHIFTING INSTEAD OF \.
+HITTING SHIFT/RETURN ON A DATAPOINT WILL DO WHAT YOU MEANT.
+WHEN YOU ARE USING A DISPLAY TERMINAL AND THE FOREIGN HOST OUTPUTS
+A FORM FEED OR RUNS OFF THE SCREEN,
+TN6 WILL SAY "--MORE--".  VALID RESPONSES ARE P (NEW PAGE),
+T (GO TO TOP OF SCREEN WITHOUT ERASING), OR S (SCROLL -- WON'T
+WORK UNTIL ITS SUPPORTS ^P>.)
+
+THE FOLLOWING COMMANDS ARE AVAILABLE.  TO ENTER A COMMAND
+HIT CTRL/UP-ARROW AND ENTER A COMMAND LINE (ECHOS AT THE
+BOTTOM OF THE SCREEN.)  HIT CTRL/K TO LEAVE COMMAND MODE
+WITHOUT TYPING A COMMAND.  IN COMMAND MODE, HIT QUESTION
+MARK FOR HELP.
+COMMANDS MARKED WITH AN ASTERISK REQUIRE AN ARGUMENT
+WHICH HAS TO BE EITHER THE WORD ON OR THE WORD OFF.
+
+ATTACH	    DO :ATTACH - GETS RID OF HACTRN.
+ATTN	    SEND ATTENTION SIGNAL.
+*BOTTOM	    CONTROLS BOTTOM-LINE USE BY COMMUNICATE MODE.
+CLOSE	    CLOSE THE CONNECTION
+DDT	    GO TO DDT.  USE P TO RESUME TN6
+*ECHO	    TURN LOCAL ECHO ON/OFF.
+EXIT	    :KILLS TN6.
+*FFMORE	    CONTROLS WHETHER ^L OUTPUT WAITS BEFORE ERASING SCREEN
+*FILE	    CONTROLS WRITING OF NETOUT > FILE.
+LOUD	    TYPE OUT.
+NEWTTY	    DECLARE THAT :TCTYP HAS BEEN USED, ETC.
+PROCED	    GIVE TTY DO DDT.
+QUIT	    SEND NETWORK ATTENTION SIGNAL.
+REINIT	    RESTART PROGRAM.
+SILENT	    DON'T TYPE OUT
+SOFT	    DON'T TYPE OUT
+TAB10	    TEN COLUMN TABS
+TAB8	    EIGHT COLUMN TABS
+*TIP        CONTROLS TIP-SLAVE MODE, SEE BELOW.
+
+
+
+
+		- CONTROL CHARACTERS -
+
+^A  ATTENTION		^K  DISCARD INPUT	^L  LOWER CASE
+^O  UNDERLINE		^P  ERASE SCREEN	^Q  QUOTE CHAR.
+^S  STOP TYPING		^U  UPPER CASE		^V  REDISPLAY INPUT
+^^  COMMAND MODE	RUBOUT  ERASE CHAR.	CR  SEND LINE
+LF  SEND INPUT WITH NO NEWLINE
+
+
+THE NAME OF THE HOST TO BE ATTACHED TO MAY BE ENTERED EITHER
+ON THE JOB-COMMAND-LINE OR IN RESPONSE TO "HOST="
+YOU MAY GIVE A HOST NUMBER OR A HOST NAME.  NUMBERS ARE IN
+OCTAL UNLESS FOLLOWED BY A DECIMAL POINT, WHICH MAKES THEM
+DECIMAL.  TO CONNECT TO A FUNNY SOCKET ENTER THE SOCKET
+NUMBER, A COMMA, AND THE HOST NAME OR NUMBER.
+TO CONNECT TO A TIP PORT ENTER THE PORT NUMBER, A SEMICOLON,
+AND THE TIP NAME OR NUMBER.
+   IF YOU GIVE AN EXCLAMATION POINT TN6 WILL KEEP TRYING
+TO GET THROUGH, IF THE HOST IS DEAD OR NOT ANSWERING.
+   WHEN ENTERING A HOST NAME, TN6 WILL FEEP AT YOU IF
+YOU ENTER A CHARACTER WHICH DOESN'T MATCH.  SPACE COMPLETES
+THE NAME OR FEEPS IF IT IS AMBIGUOUS.  QUESTION MARK OR
+ALTMODE LISTS ALL POSSIBLE COMPLETIONS.  IF GIVEN INITIALLY,
+ALL THE HOSTS IN THE WORLD ARE LISTED.
+   COMPLETE THE HOST NAME WITH A CARRIAGE RETURN.
+   RUBOUT GIVES YOU A CHANCE TO START OVER IF YOU ERR.
+
+   THE TIP ON COMMAND ALLOWS YOU TO SLAVE A TIP PORT
+TO YOUR CONSOLE.  THE COMMAND ASKS FOR THE TIP NAME
+AND PORT NUMBER.  THE SLAVED TIP PORT WILL TYPE OUT
+A SCRIPT OF ALL I/O.  YOU CAN USE A SILENT COMMAND
+TO SHUT OFF TYPING ON YOUR OWN CONSOLE.
+INPUT FROM THE TIP IS NOT ACCEPTED.
+TYPE TIP OFF TO FLUSH THIS.  NOTE:  OUTPUT IS SENT TO
+THE TIP JUST AS IT IS RECEIVED FROM FOREIGN HOST.
+NO PROCESSING OF TABS, ETC. IS DONE.
+IF YOU GET AN IOC. ERROR WHEN YOU GIVE THIS COMMAND,
+TYPE P AND YOU WILL THEN WIN.  SOMEDAY I WILL FIX THIS BUG.
